• May 2021 Conditions letter from the San Joaquin County Environmental Health <br />Department regarding S00013950 and PA -2000174, located at 4082 S. State <br />Route 99 East Frontage. The letter indicates that an "existing water well is <br />located on the property line of APN: 179-172-56 & 179-172-54." The letter <br />requires the project proponent to destroy the well or adjust the property lines. <br />These records have been attached in Appendix 4 of this report. <br />Water Sample <br />There are no active wells on the Site. No water sample was collected as part of this <br />investigation. <br />Soil Profile and Geologic Information <br />The Site is depicted on the Geologic map of the San Francisco -San Jose quadrangle, <br />California (Wagner et. al, 1991). The Site is depicted within a map unit of the Modesto <br />formation (Plate 9). <br />The surface and near surface soils located at the Site are reported by the USDA Web <br />Soil Survey to be composed of Jacktone clay (Plate 10) (USDA, 2020). The table below <br />presents some selected properties of this soil: <br />Table 1.

The boring <br />was four inches in diameter, 3.44 feet deep, and was excavated by hand auger (Table <br />2). <br />LOGE 2201 Page 5 <br />
